摘　　要：激光光束指向控制系统是通过对激光光束偏转执行机构的控制,实现激光光束稳定指向目标的系统.当激光光束指向控制系统被应用于恶劣环境时,应考虑环境对系统造成的不利影响,消除激光光束的指向误差.激光光束指向控制系统采用了基于比例-微分-积分(PID)控制器和滑模控制器的控制策略,用于提高其动态和静态性能.最后,将PID控制器和滑模控制器在不同状态下的优势相结合,提出了复合控制策略.通过实验对比分析,复合控制策略比单一控制策略具有更好的控制性能,可以满足不同工况下的激光光束指向作业.The laser beam pointing control system is a system that achieves stable pointing of the laser beam to the target by controlling the laser beam deflection actuator.When the laser beam pointing control system is applied in harsh environments,the adverse effects of the environment on the system should be considered and the pointing error of the laser beam should be eliminated.The laser beam pointing control system adopts a control strategy based on proportional-integral-derivative(PID)controller and sliding mode controller to improve its dynamic and static performance.Finally,the advantages of PID controller and sliding mode controller in different states are combined to propose a composite control strategy.Through experimental comparative analysis,the composite control strategy has better control performance than a single control strategy and can meet the laser beam pointing requirements in different operating conditions.
